Irritated with friend getting BFP

Tell me I’m out of line if I am... I try to be happy for everyone who’s announcing they’re pregnant. I don’t think I “deserve” to be pregnant more than anyone else, no matter how long I’ve been trying more than they have but I can’t help but be pissed off that my my friend is pregnant. I was so happy for her & her boyfriend to be having another baby until she told me that she cheated on him and it’s probably not his. I’m just so irritated that she cheats on her loving boyfriend once & gets pregnant with another man’s baby 🙄 Every baby deserves to be loved and celebrated but I just can’t seem to bring myself to go to her gender reveal in a few weeks.
